Product information “BRESSER Spezial Astro 25×70 Binoculars”
SPEZIAL ASTRO binoculars from BRESSER are ideal for astronomy and landscape observation.
Thanks to fully multi coated Bak-4 glass material and the extra large objective lens diameter, these binoculars provide bright and high resolution images.
The high 25x magnification it is convenient not only for observing astronomical objects, but is also practical for viewing distant terrestrial objects too. Due to a very high reduction of stray light, by multi coating all air to glass surfaces, the binoculars deliver the best possible performance and excellent contrast.

Diopter compensation and foldable rubber eyecups give eye glass wearers the possibility of making the best use of these optics’ field of view.
With the tripod thread in the lengthened centre axis, the SPEZIAL ASTRO can be mounted onto any photographic tripod. For tripod use you need the optional available tripod adapter (part No. 4914925). The use of a tripod is highly recommended with these binoculars, as at the high magnification of 25x it’s difficult to maintain a steady image by hand holding (though this is possible for short periods).
